Application led October 2, 1920. Serial No. 414,306.

To all 'whom t may concern:

Be it known that I, CHARLES S. DAHL- QUisT, a citizenl of the United States, and a.

resident of Cleveland, county of Cuyahoga,

One of the objects of the invention is toy provide in a driving axle means whereby copious quantities flected from one of the gears to the bearings and` the driving means.

Other objects of the invention and the features of novelty will be apparent from the following description taken in connection with the accompanying drawings, wherein I have described and illustrated m invention, as applied to an axle of the worm gear drive type. In the drawings Figure 1 is a transverse section through van axle embodyi g the invention, the section being taken in t e plane of the worm axis;

Fig. 2 is a plan view of one of the deflectors; and j Fig. 3 is a similar view of the other dellector.

Referring to the'drawings, 10 indicates the axle housing, which, in the form illustrated, has an opening 11 at its top side, this opening being closed by a cover plate 12which carries brackets 13 on the interior of the housing.- These brackets, respectively support bearings for the differential gearing 14, which is adapted to drive shafts extending to the wheels, in the usual manner. The details of the vdifferential mechanism may be of any preferred design, and the description of such details is omitted because they form no part of the present invention. Thel cover plate 12 has an upward extension or wall 15 forming a chamber 16 which conand the differential gearing 14l projects,

in wall 15, upwardl into mesh with the worm 17. The worm 1 may be lintegral with or secured on a suitable shaft 20, as preferred. The housing 10 Ais provided with an opening 18 which is usually closedby a plug 19, this opening being for the purpose of supplying lubricant lto the interior of the housing. The plug 19 Speclfcation'of Letters Patent.

'may be conveniently threaded for engaging in the threads of the opening 18. The shaft 20 is supported in suitable bearings 21 and 22 arranged on opposite sides of the worm 17 and'suitably supported in cups 23 arranged in the ends of the chamber 16. The vcups 23 have their outer ends closed by suitable caps 24 and 25. The shaft 20 has an extension 26 for connection with the propeller' shaft of the vehicle. In order to convey the lubricant to the bearing 21, I have provided a member consisting of a delector or plate 27 and legs 28. The delector may be held in position by suitable means, such' as the bolts 30 threaded inthe cover plate 12 and passing through tllietopenings 29 of the legs 28. The defiector p a e `3l extending at an angle to the plate 27 and y suitably secured to the legs 28, by welding or otherwise, and is also provided with a flange 32 which extends in'close proximity to the gear 14. The deflector 27 is cut away, as shown at 33,y approximately in the formof 'a semi-circle, to enable it to fit closely to the shaft 20,and is arranged at a slight angle to a radius of the gear`14 and extends between the end of the worm 17 and the bearing 21 so as to deflect oil from the gear 14 to said bearing. The cover plate 12 has openings y34registering with openings 35 in the cups 23, forming a return-channel whereby the oil from the bearings may be returned ytothe housing. A v

Adjacent the opposite end of the worin 17 ,fa deflector plate 36 may be provided, if desired. As illustrated, this plate 36 is provided with a flange 37 extending into proximity with the gear 14 and serving to deflect oil from same. `As shown, the flange 37 and the plate 36 may extend approximately parallel, `theplate36 having a 'curved portion 38 on which the flange 37 is formed. The

plate 36 has the extensions or legs 39 provided f with the openings 40 through which the bolts 41`- threaded in the cover p ate 12 may be inserted for holding the deflector in position. A strengthenin member 42 may be .provided having t e 4suitably secured to the plate 36 for the wings 43- of said plate by spot welding or otherwise. 'Howeveig it has been found in practice that it is frequently unnecessary to provide any deilector adjacent the forward stiffening legs 42 and 27 is shown-as provided with wings i found in operation bearing 22, as

iiange 37 and the plate by the action of the gears 14 and 17 without the aid of a deflecting means.

In the operation of the device, when the vehicle is being `driven forward, the gear 14 rotates in a clockwise direction, as seen in Fig. l, the lower portion of the housing 10 being filled with lubricant approximately to the height of the opening 18, and a considerable quantity of lubricant is carried upward by said gear and deflected by the flange 32 and the plate 27 to the bearing 21. It is that a steady stream `of cool oil is thus supplied to the bearing. The same action takes place with reference to the 3 6, which supply oil to the bearing 22. By this means, therefore, the bearing is not only supplied with suiicient lubricant but is, at the same time, kept cool. As motor vehicles are driven forward, for the greater part of the time, it is found unnecessary to provide deiecting means for operation during rearward drive, sufficient lubricanty for these short periods being present in the bearing and a certain quantity will also be delivered to the bearing 22 through the adjacent openings 34 and 35 and to the bearing 21 along the shaft 20.

Having thus described my invention, what I claim is:

1.` `In mechanism of the class described, the

combination `of a housing, a gear therein, a shaft above said gear, a bearing for said shaft, and a plate extending into roximity with said gear for deflecting oil from said gear to the bearing.

2. In driving axles for motor vehicles, the

combination of a housing, a gear therein, a

shaft above the axis of the gear and having a member meshing with said gear, and a deflector extending into close proximity with adapted to deflect oil from said gear to said shaft.

3. In driving axles for motor vehicles, the combination of a housing, a g'ear therein, a shaft above the axis of the gear and having a member meshing with said gear, a bearing for said shaft and a delector extending into proximity with said gear for conveying oil therefrom to said bearing.

considerable oil is fed thereto 4. In mechanism of the class described, the combination of a housing, a shaft above said gear and having a member meshing with said gear, a bearing for said shaft, and a member mounted on said housing and straddling said gear for conveying oil from the said gear to said bearing.

5. In mechanism of the class described, the combination of a housing, a gear therein, a shaft above said gear and having a member meshing with said gear, a bearing for said shaft, and a .plate supported by said housing and extending into proximity "with the periphery of said gear for deflecting oil therefrom to said bearing.

6. In mechanism of the class described, the combination of a housing, a gear therein, a shaft above said gear and having a member meshing with said gear, a bearing for said shaft, and a deflector straddling said shaft and gear for deflecting oil into said bearing.

7 In mechanism ofthe class described, the combination of a housing, a gear therein, a shaft above said gear and having a member meshing with `said gear, a bearing for said a gear therein,

shaft, and means for defiecting oil from said i -tially of said gear.

8. In mechanism of the class described, the combination of a housing, a gear therein, a shaft above said gear and having a member meshing with said gear, a bearing for said shaft, and means for deflecting oil lfrom said gear .to said bearing comprising a plate having a wing portion extendin circumferentially of said gear, and a main portion extending at an acute angle radially of said gear.

9. In mechanism of the class described, the combination of ahousing, a gear therein, a shaft above said gear and having a member meshing with saidy gear, a bearing on said shaft at each side of said member, and plates, each having a wing extending circumferentially of said gear for delivering oil to said bearing.

In testimony whereof I aix my signature.
